319.23 Optimus requirements and setup

Hi. As I see, new driver released… Did anyone try to set it up with optimus? Does it support optimus better, then previous version(in my case failed to work at all)?

And could anyone give more or less working config examples, please.

Thanks!

And one more question, does it support optimus with kernel 3.8.X series?(kernel 3.9 is a garbage for my laptop, sound problems, CPU handle errors and system crashes… hopefully 3.10 will be better)
